12.2 Electric Potential Difference Gravitational Potential – Energy gained by change in position in a gravitation field Electric Potential of a changed object depends on its distance from another changed object (work donce in moving it there) Electric Potential Difference is the change in Electric Potential when a change is moved between two points in an Electric Field.

12.2 Electric Potential Difference
Gravitational Potential – Energy gained by change in position in a gravitation field
Electric Potential of a changed object depends on its distance from another changed object (work donce in moving it there)
Electric Potential Difference is the change in Electric Potential when a change is moved between two points in an Electric Field.
E - Joules
E.P.D – Joules/Coulomb Energy/unit change
1 Joule/ 1 Coulomb = 1 Volt = 1 Joule/Amp ． sec = 1 J/A s
V= E/Q
= W/Q 1C = 1 A s
